Find out about applying for an occupational diving Certificate of Competence (CoC).

If you work underwater as a diver breathing compressed gas from any source then you need to apply for a CoC.

For more information, including the definition of occupational diving, see Working as an occupational diver.

Types of application 

Occupational divers can apply:

  • for a new CoC
  • to renew an existing CoC before it expires
  • to add an additional category or categories to an existing CoC
  • for a replacement if their existing CoC has been lost or destroyed.

Note, renewal applications must be made before the expiry date of your current CoC. Allow plenty of time to gather all your supporting evidence and for us to process your application.

If you are applying for any of these CoCs, you can use our new online forms

  • The forms make it easier for you to complete your application form and upload all supporting documentation.
  • You will be able to track the progress of your application, including saving it and coming back to it, if you need to.

If you are unable to use the online form, you can still use the PDF form and email or post it to us.

 

What you are required to provide

To apply for a new CoC or to renew your current CoC we will need the following information. Note, you must apply for a renewal before the expiry date of your current CoC. Allow plenty of time to get your medical clearance and gather all your supporting information.

How to get a DHMS dive medical clearance certificate:

To get a DHMS medical clearance certificate you must complete:

The DHMS will assess your request and, if it is acceptable, issue the clearance certificate.
